〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 3 to 7.

In FIG. 3, reference numeral 7 indicates a code plate, and the code plate 7 in the illustrated embodiment is a disk coaxially and integrally connected to the upper end of the rotating shaft 8 of the rotary body at the left end in FIG. One rotation of rotating body 1, that is, 3
The surface display rotates once every cycle.

On this code plate 7, as shown in FIG.
Discrimination codes 9, 9 are disposed radially at equal angular intervals, corresponding to each of the three display bodies, and for distinguishing one display body from the other display bodies. The discrimination code 9 in the embodiment shown in FIG. 4 converts a discrimination code or discrimination number for distinguishing one display body from another display body into, for example, a two-digit binary number, and each digit of this binary number is “ The bit content of "0" or "1" is expressed by the presence or absence of a small hole 11 that penetrates the outer periphery of the code plate 7 in the thickness direction, and the exponent of the binary number is expressed by
This corresponds to the difference in position in the radial direction of 1. In the illustrated embodiment, when the bit content is "1", a small hole 11 is drilled at a corresponding radial position. In the display devices shown in FIGS. 1 and 2, the number of display bodies is three, so a 2-bit discrimination code is sufficient. Further, it is assumed that the discrimination code "00" is not used.

On the other hand, when one display body is in the display position, that is, when the display surfaces of the rotating bodies 1 representing one display body are on the same plane as shown in FIG. A code reading device 12 is arranged at an angular position aligned with the code 9.
As shown in FIG. 3, this code reading device 12 has a pair of blocks sandwiching the outer periphery of the code plate 7, and one block has a light source (not shown).
The other block contains two photoelectric elements each for receiving light transmitted through the small hole 11 from the light source (not shown). Then, as shown in FIG. 5, the outputs of the two photoelectric elements 13, 13 are extracted in parallel and used as a discrimination signal DS.
(Figure 6). Further, the photoelectric element 13,
13 is also supplied to an OR gate 15, and the output of this OR gate 15 is supplied to a control device 14 shown in FIG. 6 as a fixed position detection signal PS indicating that the display body is at the display position.

Next, the configuration of the control device 14 of the explanation device according to the present invention will be explained with reference to FIG.

The discrimination signal DS read from the code reading device 12 is supplied to a control circuit (hereinafter referred to as CPU) 17 via a latch circuit 16. Also,
The fixed position detection signal PS is supplied to the latch circuit 16, the discrimination signal DS is held, and the CPU
17, and its operation is switched.

On the other hand, in FIG. 6, reference numeral 18 is a storage device using a semiconductor integrated circuit (hereinafter simply referred to as IC memory).
This IC memory 18 is a collection of a plurality of unit IC memories that digitally store explanations of each display, advertisement announcements, background music, and other sounds. Among the Karuru IC memories, read-only ones are well known and are put into practical use, for example, in built-in audio warning devices in cameras, automobiles, etc., so a more detailed explanation will be omitted. Note that the length of audio that can be stored in one IC memory is usually shorter than the length of the explanation of the display on one side, but in such cases, the explanation of the display, etc. can be stored in multiple IC memories. A set of divided audio signals can be considered as one unit IC memory. In addition, IC memory is not limited to the read-only type mentioned above.
Of course, so-called EP-ROM or random access memory (RAM), which can be erased and rewritten, may also be used.

For each unit IC memory provided corresponding to each of the plurality of display bodies, the one corresponding to the display body at the display position is selected by the CPU 17 having a selection means and an audio signal reading means. The audio signal stored in the unit IC memory is sent to a speaker 22 via a digital-to-analog converter (hereinafter referred to as a D/A converter) 19 and an amplifier 21.

[Effect]

In the explanation device according to an embodiment of the present invention configured as described above, when one of the plurality of display bodies advances to the display position, the code reading device 12 outputs the discrimination signal DS corresponding to the display body. At the same time, the fixed position detection signal PS is generated. The discrimination signal DS is supplied to the CPU 17 while being held by the latch circuit 16 and the fixed position detection signal PS.

The CPU 17 receives the discrimination signal DS using the fixed position detection signal PS as an operation start signal, and first, the built-in selection means operates to select a unit IC memory corresponding to the received discrimination signal DS from the IC memory 18. Next, the reading means in the CPU 17 operates to digitally read out the audio signals sequentially from the selected unit IC memory, and send them to the D/A converter 19 at a predetermined timing, where the D/A conversion is performed. The audio signal converted into analog by the device 19 is amplified by the amplifier 21 and then supplied to the speaker 22.
The information is converted into audio, such as an explanation of the display that is currently being displayed.

When all audio signals stored in the selected unit IC memory have been read out, the next display may be displayed, or the same explanation etc. may be repeated again.

Thereafter, similar audio explanations and the like are given for each of the display bodies to be described later.

[Other Examples]

Note that the present invention is not limited to the illustrated embodiment, and can be implemented with various modifications.

For example, while the display is being converted, that is, when the fixed position detection signal PS is not generated, the speaker 22 is silent in the illustrated embodiment;
A common IC memory for background music separate from the unit IC memory is provided in the memory 18,
This music may be played while the display is being converted.

Further, the display device to which the present invention is applied is not limited to the one shown in FIGS. 1 and 2, but may be the one shown in FIG. 7, for example. This display device is made by connecting strips of five display sheets with flexible connectors to form a cylinder with a pentagonal cross section, and each pillar-like display unit is formed by a pair of triangular The rotating body 1 is constructed by extending around the outside of the sprockets 23, 23, and each rotation 1 is transmitted through the worm 4 and the worm gear 3.
It is designed to rotate in conjunction with the In this display device, the five-sided display rotates once by 5/3 rotation of the triangular sprocket 23.
By connecting the worm gear shaft and the code plate (not shown) via a reduction gear (not shown) with a reduction ratio of 5/3, it is possible to provide a code plate that rotates once for each round of the entire display body.

Furthermore, although the discrimination code 9 in the illustrated embodiment is an optical pattern formed by small holes 11 illuminated by a light source, this is achieved by attaching a small permanent magnet to the code plate 7 instead of the small holes 11. The magnetic flux may be detected by a Hall element provided in the code reading device 12, or a pin may be provided protruding in place of the small hole 11, and this pin and a micro switch attached to the code reading device 12 may be detected. The microswitch may be driven by engaging the actuator of the microswitch. In short, the discrimination code 9 may be in any form as long as it is recorded in a mechanically readable form.

〔effect〕

As is clear from the above explanation, the present invention provides a code plate that rotates once for each cycle in which all the display bodies go around, and displays on this code plate to distinguish one display body from other display bodies. The system has the same number of discrimination codes as the display body, and reads the discrimination code corresponding to the display body at the display position and selects the corresponding IC memory, so the correspondence between the display body and its audio explanation etc. is accurate.

In addition, since audio signals such as explanations are recorded in IC memory, it is not only possible to completely prevent deterioration of sound quality and wear and tear on the storage medium, but it is also extremely easy to cue the beginning of the audio. . Therefore, it is possible to start explaining the converted display object in a timely manner.

Furthermore, unlike magnetic tape regeneration devices, there is no need for a motor or tape drive unit that consumes a lot of power, so the power supply and the entire device can be made more compact.
It has various effects such as
